VAPOR-LAM P.

SPECIFICATION forming part of Letters Patent No. 675,638, dated June 4, 1901.

Application filed January 12, 1901. Serial No. 43,043. (No model.)

To ttZZ whom it may concern:

Be it known that I, J osnrn M. NOEL, a citizen of the United States, residing at Lilly, in the county of Cambria and State of Pennsylvania, have invented a new and useful Vapor- Lamp Burner,of which the following is a speoi= fication.

My invention relates to an improvement in vapor-lamp burners; and it consists in the peculiar construction and combination of devices hereinafter described and claimed.

In vapor-lamp burners the jet-orifice in which the point of the needle-valve operates becomes obstructed with a deposit of carbon and wholly or partially closed thereby, thus rendering it necessary to clear the said jetorifice to keep the burner in perfect condition, and in the vapor-lamp burners heretofore constructed it is difficult to clear the said jet-orifices. Furthermore, the needle-valve tends by its adjustments to enlarge the jet-orifices,and hence permitting an undue escape of gas or vapor therethrough, not only wasting the excess gas or vapor, but also decreasing the efficiency of the burner and causing it to give imperfect results.

The object of my invention is to effect improvements whereby the needle-valve may be dispensed with and the jet-orifice may be readily cleaned and kept clear of carbon and whereby the disadvantages resulting from the enlargement of the jet-orifice are obviated.

In the accompanying drawings, Figure 1 is an elevation, partlyin seotion,of a vapor-lamp burner embodying my improvements. Fig. 2 is a sectional view of the same, taken on a plane at right angles to that of Fig. 1. Fig. 3 is a horizontal sectional view taken on a plane indicated by the line ct a of Fig. 1. Fig. 4 is a sectional view of a vapor-lamp burner, illustrating a modified form of my invention. Fig. 5 is a sectional View of the same, taken on a plane indicated by the line b b of Fig. 4.

The vapor-lam p burner 1 is of the usual or may be of any preferred construction. In the embodiment of my invention I provide a detachable and adjustable piece 2, in which is the jet-orifice 3. The piece 2 may be in the form of a strip, as in Figs. 1, 2, and 3, or in the form of a disk, as in Figs. 4; and 5, and may be of any other suitable form and is preferably provided with a series of jet-orifices 3, which are adapted to be successively disposed above the valve by adjusting said strip or disk. Each orifice of the strip or disk is employed in the operation of the burner until the said orifice ceases to properly proportion the gas or vapor with the air mixed therewith and fed to the burner, and when the said orifice becomes enlarged or obstructed by the deposit of carbon the said strip or disk is adjusted in such manner as to remove the said obstructed or enlarged orifice from its position over the valve and shift another orifice into operative position. The strip or disk may be readily and cheaply manufactured, and being provided with a plurality of jet-orifioes the same may be used until all of the jet-orifices have been employed, after which if the orifices have been clogged by the carbon deposit the same may be readily cleared by removing the strip or disk from the burner; but owing to the exceedinglysmall cost of the strip or disk in practice it will perhaps be found more economical to throw away a used strip or disk and substitute a new one in its stead than to clean the used strip or disk. Any suitable means may be employed for securing and adjusting the aperture piece, strip, or disk, and I do not limit myself in this particular.

In the form of my invention shown in Figs. 1, 2, and 3 the piece 2 is in the form of a ribbon or strip placed on that portion of the burner in which the valve is located and adapted to be moved lengthwise to dispose the jet-orifices, with which it is provided, successively in position for use over the valve. A vertically-movable collar 4 is employed, which bears on the upper side of said ribbon or strip and when depressed clamps the same in position on its seat. This collar is carried by a U-shaped rocking yoke 5, the arms of which have their outer ends pivotally connected to the burner, as at 6. A lever '7 is fulcrumed to a projection 8, with which the burner is provided, as at 9, and the inner end of said lever is connected to said collar 4 by a link 10. It will be understood that by means of this lever the collar may be raised to release the orifioe-strip and permit of the adjustment thereof and depressed on the orifice-strip to secure the same at any desired adjustment. Preferably the outer arm 11 of lock the said lever, as shown in Fig. 1.

orifices 3, to be used in positioning the jetorifices on the burner when shifting or adjusting the said orifice-strip.

In the form of my invention shown in Figs. 4 and 5, in which the orifice-piece is in the form of acircular disk, the latter is pivotally mounted at its center on a support 9, with which the burner is provided, by means of a removable pin or screw 15. The plurality of jet-orifices 3 with which the said disk is provided are disposed in a circle concentric with said disk, and the latter has the nicks or marks 14 in its periphery engaged by a springdetent 16,with which the support 9 is provided. The said detent, as will be understood, serves to secure the said disk in place when any one of the jet-orifices is located in operative position on the burner. The orifice piece, strip, or disk may be made of steel or any other suitable metal or material, and I do not limit myself in this particular. In this form of myinvention the valve 16, which is screwed in the body of the burner, as at 17, is hollow, its bore 18 communicating with the vapor-duct l9. Formed with the body of the burner above the valve 16 is a fixed seat 20, having a central opening 21. One side of the disk or jet-orifice piece is disposed between the said valve and the said fixed seat 20, and the disk or jet-orifice piece is clamped in position when set with one of its j et-orifices registering with the bore of the screw-valve by means of the latter, the said Valve clamping the jet-orifice piece or disk firmly against the seat 20 and effecting a vapor-tight joint with said jet-orifice piece or disk, as will be understood.

It will be further understood that I dispense with the needle-valve usually employed in a burner of this class. The screw-valve may be employed for clamping the stripshaped orifice-piece shown in Fig. l, as well as the disk-shaped orifice-piece.

Having thus described my invention, I claim- 1. A vapor-lamp burner having a vaporduct provided with a fixed seat, in combination with a jet-orifice piece having a plurality of jet-orifices, and means to clamp said jet-orifice piece on said seat and eifect a vapor-tight joint therewith, substantially as described.

2. A vapor-lamp burner having a vapor duct provided with a fixed seat, in combination with an adjustable jet-orifice piece, having a plurality of jet-orifices and detentnotches, means to clamp saidjet-orifice piece on said seat, and efiect a vapor-tight joint therewith, and a detent to engage said detent-notches of said jet-orifice piece, for the purpose set forth, substantially as described.

3. A vapor-burnerhavinga vapor-duct provided with a fixed seat, in combination with an adjustable jet-orifice piece having a plurality of jet-orifices, a movable clamping element to secure said jet-orifice piece on said seat and effect a vapoistight joint therewith, and means to operate said movable clamping element, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in the presence of two witnesses.
